Light steel keel partitions and finished partitions
- Light steel keel partition is one of the most common decoration projects in the field of decoration and decoration. It is made of light steel keel as the basic skeleton, the surface gypsum board is made of wall layer and fixed to the top and top of the building. Wall; it needs to use talcum powder, such as putty layer, latex paint or wallpaper as a surface decoration, are produced on-site.s
How to construct double - sided double gypsum board partition wall
- Line: according to the design and construction plans, in accordance with the keel width of the elastic line, has been done on the ground or ridge to release the wall position line, door and window openings border line, and put the top, wall keel position edge. To cover the panel of the long, wide sub-file, to ensure that the keel position is correct.
Heaven and earth keel installation, along the ball line fixed top, to keel, fixed point spacing should not be greater than 600mm, keel docking should remain straight.
Fixed keel keel, keel the end should be fixed, fixed should be solid. Wall, column edge keel with nails or wood screws and walls, column fixed, nail distance of 1000mm.s

75 series of light steel keel wall double-sided double-layer 12 thick plaster board filled with sound insulation noise can reach the number of decibels
- Theoretically, the main factors influencing the sound insulation of the gypsum board wall are as follows:
1) the law of quality: there is a common law for the insulation of the partition, that is, the heavier the material (the greater the surface density) the better the sound insulation. For a single layer of dense uniform wall, surface density for each doubled, the sound insulation in the theoretical increase of 6dB, this law is the law of quality. For the double layer of gypsum board wall, the law of quality plays an important role, that is, to increase the number of layers or thickness of the board can be improved sound insulation. As the keel double wall system sound vibration form is very complex, so the embodiment of the law of quality than the simple single-wall complex.
2) Resonant frequency: any partition wall there is an inherent resonance frequency, when the sound wave frequency and wall resonance frequency, the wall as a whole resonate, the frequency of the sound insulation will be greatly reduced.s
